We proudly offer free shipping on most products in our massive inventory. Products qualifying for free shipping are clearly noted with a "Ships4Free" checkout button. This promotion applies to qualifying products shipped via standard ground shipping to addresses within the lower 48 states only. Free shipping offer does not apply to expedited shipping. HI, AK, and international orders excluded. Products which do not qualify for free shipping are clearly noted with an "Add to Cart" checkout button. To maximize savings for our valued customers, actual shipping cost for pond liner and other oversize / heavy products is manually calculated after an order is received. If you would like to receive a shipping quote for an oversize product before making a purchase, please contact us.
